How to add vertical scrolling to a bar chart?

[tejajag]

I am trying to display a bar chart with only 10 events displayed at a time and is vertically scrollable to view all the events.

Following approach worked for me!

1. set the height option in the xml such that it displays only 10/required number of results
2. set a token in the xml that stores the count of query results(use $job.resultCount$) when the query execution is in progress/done.
3. use Java Script to get the count token value using splunkJS defaultTokenModel and calculate the height to set based on the result count and then set the height on $('#bar.viz-controller') element.
